Don't cast a great hands-on resource aside! Scholars learn about the process of casting by actually trying out an example. Plaster of Paris and cookie cutter molds help them complete the activity.

Instructions for two terrific ancient history lessons for your primary paleontologists are provided in this resource. The first involves the creation of fossil cast replicas using plaster of Paris. The directions are detailed, but the...

A fossil is worth a thousand words! Individuals craft their own amber fossil of an insect in addition to molds and casts of seashells. A third activity takes the lesson a notch higher: Learners measure stride lengths between tracks and...

Explore the unique characteristics of polymers. A complete lesson begins with a presentation introducing polymers. Following the presentation, young scientists develop a laboratory plan for creating substances using polymers. They...

A lever comes in handy when scholars build a launcher for a ping-pong ball. They test the launcher and redesign it to send the ball higher or to accommodate a tennis ball. This is the third lesson in a five-part unit.

Sunrise, sunset ... swiftly move the shadows! Pupils practice comparing shadow length data with a hands-on activity. The resource allows users to examine and measure the shadow cast by a stick as the sun moves overhead before testing...

Young scholars create science presentations. In this science unit lesson, middle school students create a presentation on an elementary science concept. The presentations are turned into podcasts for the access of elementary school...

Pupils test worm castings for content and use them to grow seeds. They hypothesize which castings best sustain seed growth. They observe growing plants to test their hypotheses. Later they graph their data.

Students make a plaster cast of tree bark. They use plaster casts of tree bark to make a simple classification system. Also, they use plaster casts of tree bark to identify individual trees.

Review the steps for preserving wildlife tracks and then take ecologists outdoors to create plaster casts. This lesson plan is best used at an environmental or outdoor school situation since wildlife footprints aren't easily located...

Students examine and define fossils. They create their own impressions and molds in clay and candle wax, making external and internal molds.

By using the Internet, hands-on activities, video, and cooperative learning, pupils look into the conditions in which light casts shadows on objects. The lesson includes fabulous hands-on activities, art projects, worksheets, and reource...

Strengthen understanding of the musculoskeletal system with a structured lesson! Begin with a discussion of bones, joints, and muscles. Have small groups read assigned articles and watch videos to gather information and then write a...

An exceptionally creative approach is taken to assessing your biologists' grasp of natural selection concepts. They are to imagine hosting Charles Darwin for dinner and having, to their surpise, a few other noted scientists crash the...

Shine some light on the topic of seasonal change with this collection of activities. Whether it's by measuring the change in the length of their shadows, or modeling the earth's orbit around the sun using a lamp and a globe, these...

Can you catch the same cold twice? Elementary and middle schoolers learn about what happens when a virus attacks their bodies, and how the immune system never forgets a virus, with an entertaining comic book. The packet includes...

How do the moon, sun, and Earth line up to create eclipses? Why do the seasons change throughout a year? The answers to these questions are explained through this series of slides. This apt presentation outlines information using bullet...

Students examine the discipline of biomedical engineering or bioengineering. They complete worksheets by participating in reading background information and completing a hands on activity. They design a prototype of a cast to set a...

Searching for a fairly easy demonstration of how oxidation triggers rust formation? The demonstration allows high school chemists to witness the rusting of metals, as large and small objects are held into a flame while triggering the...

Students explore the dilemma of bioethics. Students review a cast study on a bioethical topic. They research the facts, values, and stakemakers in the controversial debate. Students consider the consequences and discuss their findings...

Although this was written to accompany a specific textbook, the information can illustrate wave motion for any advanced level physics course. The slides are simple, use plain but colorful fonts, and include diagrams and pictures to...

Science pupils choose from twelve questions about five different types of fuel: hydrogen, ethanol, crude oil, natural gas, and coal. They construct a table to compare them and then determine the best fuel. Your physical science class...
